Please be welcome on the (van)Middelkoop site. Their eldest forefathers were named after the polders where they, or there fathers were grown up. The polders are located in the heart of Holland, between the rivers Linge and Lek. The area is called 'Vijfheerenlanden', as five lords agreed in the late Middle-ages about a system to control the waterlevels and how to get rid of the access water coming from the east (higher lands) of from heaven. An other source of the surname might be the owenership of a small part of the polder Voorkoop between Culemborg and Beusichem. This part was also named 'de Middelkoop'.
